Breaking Down the Mexican National ID Number

The National ID Number or CURP (Clave Única de Registro de Población) is likely one of the commonest ID numbers for individuals in Mexico. It is similar in use to the U.S. Social Security Number, but unlike the SSN, it is algorithmically generated utilizing the person’s full legal name and personal information. Understanding Mexican ID Number development may also help reveal key details about people and allow analysts to easily identify false ID numbers.

Naming Conventions in Latin America

Earlier than we focus on the construction of CURPs, it is essential to talk about naming conventions in Latin America. In Spanish-speaking jurisdictions, names are typically comprised of three parts.

An individual’s given name, additionally known as a first name, is either a single name, corresponding to Alejandra, or more commonly a compound name with or more names, corresponding to Francisco Enrique.

The given name is followed by the paternal surname, then the maternal surname. Paternal and material surnames might be compound, but this is less common.

For example, let’s look at professional Mexican soccer player Rafael Márquez Álvarez. The U.S. Division of the Treasury sanctioned him in 2017 for serving as a frontman and holding assets for lengthy-time drug kingpin Raúl Flores Hernández, the leader of the Flores Drug Trafficking Organization.

If we break down his name into its three parts, his given name is Rafael, his paternal surname is Márquez, and his maternal surname is Álvarez.

Deciphering the Mexican National ID Number

The Mexican National ID Number (CURP) is an eighteen character alphanumeric code. It is structured as follows:

4 letters from the particular person’s authorized name: – First letter of the paternal surname – First inside vowel of the paternal surname – First letter of the maternal surname – First letter of the given name

Six numbers which might be the person’s date of delivery in YYMMDD format

One letter describing the person’s gender: “H” for male (hombre) and “M” for female (mujer)

Two letters which can be the two-letter state abbreviation for the state the place the particular person was born; if the individual was born outside of Mexico, the abbreviation “NE” shall be used for Nacido en el Extranjero (born abroad)

Three letters from the particular person’s authorized name: – First inner consonant of the paternal surname – First inside consonant of the maternal surname – First internal consonant of the given name

One character to avoid duplicate CURPs among people who have related names, places of delivery, and dates of beginning; the character is a number that ranges from zero to 9 for people born earlier than 2000 and a letter from A to Z for people born since 2000

One character that may be a checksum
